ReSound LiNX Quattro 9 hearing aids are compatible with most modern smartphones. The Smart 3D app was developed for use with the Android and iOS (Apple) marketplace. This downloadable app lets you control your hearing aids utilizing your smartphone. On both mobile phone platforms, the apps provide direct connectivity from smartphones to the hearing aids without the need for any additional (Streaming) devices.

Features of the Smart App

  • Adjust hearing aid volume controls.
  • Change hearing aid programs for different environments.
  • Adjust hearing aid equalizer
  • Initiate hearing aid remote support. (Remote adjustments from HearSource pushed through your smartphone to your hearing aids.)

Made for Android and iPhone Hearing Aids

LiNX was the first “Made for iPhone” hearing aid and is now the first “Made For Android* hearing aid on the market. The ability to stream calls, music and other audio directly to hearing aids was revolutionary for the time. Before the launch of LiNX, many hearing aids had wireless capabilities, but they all required the use of a hearing aid streaming accessory.

When ReSound started working directly with Apple to allow streaming directly from an iPhone to Bluetooth connected hearing aids, consumers instantly took notice. Now the direct streaming capability is available for use with the Google Pixel 3, 3a, 4, & 4a Smartphones that have been updated to Android 10.

Hearing Aid Streaming from Android

ReSound LiNX Quattro 9 direct streaming capabilities are currently limited to the iPhone, and Google Pixel 3, 3a, 4, & 4a Smartphones that have been updated to Android 10. Direct streaming from an iPhone or Google Pixel 3, 3a, 4, & 4a Smartphones to these hearing aids requires NO streamer or other intermediary device.

ReSound Phone Clip+

Other Android users that want to stream from their phone will have to purchase a hearing aid streaming accessory such as the Phone Clip+. This allows Android users to send an audio signal from their mobile phone to their hearing aids.

It’s nice to have direct streaming from the phone, but using a streaming accessory has its advantages. If you desire a truly hands free experience using a hearing aid, a streaming accessory is a must. Usually this technology is discreetly worn on the body and allows you to connect your hearing aids to a smartphone up to 30 feet away. With the ability to answer phone calls via the streamer, actually having your phone on your person is no longer necessary.

Even though iPhones have direct streaming to hearing aids, the actual iPhones still have to be answered and talked into. Wireless streamers allow for the actual phone to be left in the pocket or anywhere nearby. Where this specific technology can come in handy is if you have take a lot of phone calls and really need a hands free experience. We have also found that some of our clientele that have mobility issues enjoy this accessory and technology.

Tinnitus Management and Relief

With 80% of hearing loss cases existing alongside tinnitus (ringing or buzzing in the ears), the ReSound LiNX Quattro 9 addresses this condition head-on with their “Relief” feature. This sophisticated tinnitus management system masks the tinnitus sound and provides a collection of pre-programmed synthetic sounds to aid in tinnitus desensitizing.

Unite Accessories

ReSound Unite Accessories

Rechargeable Hearing Aids

  1. Fred V. From Carrolton, TX.

    My third set of hearing aids in my life. These are by far the best in every aspect. They connect right to my iPhone, I love that. They also automatically change when I move from one sound environment to another. They are comfortable and natural sounding. These are my first rechargeable hearing aids and I really like that feature also. All in all, a perfect set of hearing aid for me.

  2. Penny J. From Edmonds, WA.

    Wonderful hearing aids in every sense of the word.

  3. Laura T. From College Park, MD.

    I have worn these hearing aids for about a year now and am just now getting around to writing a review. They have been a fantastic asset in my life. I still work and have grown children with 8 grandchildren. My life and house can be a hearing challenge for me. At work, I hear the phone well. The streaming of phone calls from iPhone is awesome. I feel much more confident in my interactions with others in both work and home environments.

    HearSource has been a pleasure to work with. I can count on them and their support.

  4. Linda A. From Albuquerque, NM.

    I’ve worn several different pairs of hearing aids over the past 35 years, these ReSound LiNX Quattro 9 hearing aids allow me to hear things I’ve not been able to hear before. Thank you to Hearsource for their great support and patience with me. They have been awesome to work with.

  5. James M. From Scranton, PA.

    When I finally decided to get hearing aids I was totally confused. I didn’t know where to start. I did start by walking into a local hearing aid office and had my hearing tested. I was told I needed hearing aids. Then they told me the price. I was “gob smacked”. Hearing aids were totally out of my budget. So I left their office a bit dejected. My daughter was actually the one who suggested that I check out I am so glad that I did. They requested that I send them a copy of my hearing test. Based on the hearing test and a short conversation with one of their staff I selected the ReSound LiNX Quattro 9 rechargeable hearing aids, again based on my hearing loss and lifestyle. The aids arrived in just five days programmed to the submitted hearing test. They were pretty close. After just one remote support care/programming session, they sound pretty much perfect.

    Thank you HearSource for allowing to be able to afford hearing aids of this caliber and for the fine service and support that you provide. I am also a true believer in this technology and I am their customer for life.

  6. Eric G. From Phoenix, AZ

    My local audiologist, which I have gone to for years, advised me to NOT to buy online hearing aids. She was WRONG. I promise you, HearSource service and support is outstanding. My first remote support session to fine-tune the sound adjustments, done by the audiologist, was outstanding. The best customer service that I have EVER received. The ReSound Quattro 9 hearing aids arrived in just 3 days from my order. The package arrived with a carrying case, small toolset, charger, extra wax guards, and an assortment of receiver tips. I have since had another remote programming session that was provided on the same day that I requested it. I am very pleased with the performance of the hearing aids and the ability to create a custom profile for my specific situation and the ability to adjust the equalizer to suit the environment. I will also add that the music profile provided by the audiologist is just superb. HearSource, and the ReSound Quattro 9 hearing aids are both superb. I am a customer for life.

  7. Wei W. From San Francisco, CA.

    ReSound has always made an excellent product and Quattro 9 is no exception. The sound quality is on par with other premium plus level hearing aids. Pairing with my iPhone took several attempts. First-try, it caught the left aid and not the right. Then the second go-round it caught the right aid and not the left. 3rd try, it paired with both aids. I’m not sure that was an issue with the hearing aids or the phone. The HearSource remote support has been excellent and my technician (Aaron) has always been thorough and patient with me. So a 4-star rating for ReSound Quattro 9’s and a 5-star rating for HearSource.

  8. Jeffrey B. From Minneapolis, MN.

    I rated these ReSound Quattro 9 hearing aids and HearSource 5 stars because they deserve it. I am not the easiest customer to satisfy. The HearSource people have been good to deal with and they these hearing aids adjusted perfectly for my hearing loss. They preprogrammed them for me based on the hearing test that I uploaded to them prior to shipping them to me. They came to me and arrived at my residence on the 4th business days after I placed my order. They were great right out of the box. I have asked HearSource to provide 2 minor sound adjustments for me. They (the sound adjustments) were available to me the same day that I requested them. I saved almost $4,000 buying through HearSource.

  9. Andrew T. From Bushnell, FL.

    ReSound Quattro 9 hearing aids use rechargeable batteries, but only some of them do, you have to decide if you want rechargeable hearing aid batteries or regular zinc-air hearing aid batteries. You gotta shop around and investigate as to what’s available, what’s best for your hearing loss and pricing. Prices vary widely. After much research, I went with HearSource because of their pricing and their support service. I have been very pleased with these ReSound hearing aids and the service that HearSource has provided me.

  10. Homer D. From Blue Springs, MO.

    Very good hearing aids. HearSource is a good sales & service company too. Great pricing here.

  11. Ken from Foxborough, MA

    I just received my ReSound LiNX Quattro 9 hearing aids from HearSource. I am so pleased. I can hear the wind, my footsteps, the birds, my cars turn signal indicator ticking. Great hearing aids that fit comfortably behind my ears even while wearing my glasses. Bluetooth technology lets me connect and stream phone calls from my iPhone. These are rechargeable hearing aids, so no replacing batteries. I can control the sound using an app on my phone. Thank you for providing top of the line equipment for such a reasonable price.

  12. Oliver Banks

    Excellent hearing aids. I have a severe high frequency hearing loss with normal hearing in the low frequencies. I don’t struggle with the volume of sound, just the understanding of speech, particularly when in groups or where background noise is present. These are my first hearing aids, so I relied totally on the recommendation of the HearSource representatives. Both HearSource and these resound hearing aids hit the ball out of the park…. Home run. I love em. I hear well while wearing them. Background noise isn’t a bother. I use my Android Google Pixel 4 smartphone to stream phone calls, listen to music, and control the functionality of the hearing aids. 5 stars isn’t a high enough rating for these.

    P.S. I like the HearSource prices and these hearing are rechargeable also, a bonus included at no charge.

  13. Kurt Nilssen, Norway.

    Yess, high quality! BT communication works OK, but not 100%. Now and then challenging with the «handshake» between hearing aid and my iPhone, iPad. I dont know the price, in Norway we can have these type of tools for free!

  14. George M

    Amazing hearing aids! These hearing aids were half the price of my local provider.
